RobboLito - Versione E1

RobboLito



RobboLito is an extremely strong open-source UCI chess engine by:
Yakov Petrovich Golyadkin, Igor Igorovich Igoronov, and Roberto Pescatore

description:
RobboLito is a UCI windows 'console' application, meaning that it has no GUI (graphical user interface). there are several free programs that provide a GUI, along with a rich set of user-friendly features. three of the most popular free GUIs are: winboard, chess-gui, and arena

note:
RobboLito does not yet support:
multiPV
own book
egbbs
tablebases
multiple CPUs/cores
chess variants

rating:
~ 3300 ELO

download
:

RobboLito 0.085e1 w32
(includes source code and optimized w32 executable)

RobboLito 0.085e1 x64
a fast bankuss 64-bit PGO compile!
(includes optimized x64 executable only)

RobboLito
has been completely translated from Italo-Albanian to English, and it does not include any of RobboLito's original tablebase code (v. 0.084). these tablebases are not needed, as RobboLito demonstrates extremely strong endgame play without them. the engine recognizes many draws and solves endgame positions that even Rybka 3 and other commercial programs miss.



RobboLito UCI Options:

MPH (Move on Ponderhit) -> Never, Sometimes, Always ...if predicted move is played by opponent, make move
default = 'Sometimes'...if move = EASY (i.e. when it's a no brainer!)

OTM (Original Time Management) -> original agressive algorithm from Robbo 0.084 -> thru d3. default = 'off'

OTF (Original Time Factor) is a variable used to determine the move time for blitz (it divides the max time) default = 25

here is the corresponding code:
TIME_DESIRED = TIME_MAX /
OTF + INCREMENT;
i.e. the higher OTF is, the less time allocated per move
RobboLito is not a 'clone' of Rybka 3, as some may like you think...it's very different.

detailed history/major changes:

RobboLito 0.085e1
UCI Ponderhit Move -> Move on Ponderhit

no longer loses lightning/blitz no increment games

RobboLito 0.085e
1st release of 'e' series, baseline version
will be starting point for multiPV and SMP implementation enhanced time management is 'on' by default (this seems to be a more conservative/safer TM than OTM)

OTM now 'really' true by default

RobboLito 0.085d11
OTM default
OTF default = 25
